Microsoft Fabric Tour 2025 in Redmond, WA at the Microsoft Reactor Building
03 June 2025
It was a beautiful Saturday on May 31st in Redmond, Washington when over 600 people descended on the Microsoft Reactor Building to hear great speakers talking about Microsoft Fabric.
The speakers and attendees were great. The speakers made time for questions and the questions were asked and answered with heartfelt passion and conviction. The organizers were also treated to some extra hustle requirements when the total number of attends was more than twice than was expected a week before kickoff.
As a person who doesn't always spend most of their time in the world of "Data" I learned a lot more about one of the most exciting platforms that is not discussed enough. Everyone can rave about AI, but data is the blood that drives the beating hearts and data is often found everywhere.
This is why it was with great to learn about the expansion of data mirroring and the reach for Microsoft OneLake. Sources that many clients already own such as Microsoft Dataverse, Snowflake, Azure SQL and SQL Server on-premises (accessed using the Azure Data Gateway).
Other key technology advances were also shared.
Security continues to be a focus and enhanced security features have been added including the ability for more rich administration. This includes defining access permissions once and having them consistently applied in numerous places.
There was also a significant amount of time spent on near Real-Time processing and productivity of queries. It was great to hear people taking performance seriously. In the past performance often becomes the forgotten stepchild that only gets considered when there is a problem or gets overlooked because of the advancement in hardware, but bottlenecks are not just hardware!
Microsoft Fabric also includes Microsoft Azure Synapse Analytics and when I first started learning about and watching the use of Azure Synapse Analytics, I watched the deep, deep technical gurus climb the steep learning curve, so it was nice to hear that this learning curve is also being addressed. As some would say, the path to simplicity must first deep dive into the complexity. "Simple" is by far not the correct term, but as technology matures, grace and usefulness does get impacted by complexity, so leaning towards use and usability continues to be seen from the Microsoft development teams.
As an application focused resource, I continue to watch the new features that are related to business rules and as such the announcement that Microsoft Fabric now supports user data functions was an interesting one. To get "User Data Functions" summarized I asked for a little help (thank you ChatGPT) and here is what I found out "User Data Functions are reusable, parameterized functions that you define using T-SQL or Spark (PySpark/Scala) and then call from various components in Fabric. They encapsulate business rules, data transformations, or logic that you want to apply consistently across your data environment." so these have some very interesting potential.
and down the rabbit hole when I asked how UDFs related to or could be used with the Power Platform
"User Data Functions (UDFs) are a Microsoft Fabric feature and not native to the Power Platform, you can bridge them into Power Platform solutions—particularly when working with Power BI, Power Apps, or Power Automate that consume or manipulate data from Microsoft Fabric, OneLake, or Synapse Lakehouse."
Platform | How UDFs Are Used |
---|---|
Power BI | Directly in semantic models, Lakehouse queries, or reports via SQL endpoints. |
Power Apps | Indirectly by connecting to Fabric-enriched tables or APIs. |
Power Automate | Triggers Fabric pipelines or notebooks where UDFs apply logic, with results flowing back. |
Dataverse | Can act as a bridge, syncing UDF-enriched data between Fabric and Power Platform. |
One of the coolest benefits for companies working with the Microsoft Stack is that it is always pushing the bleeding edge and always offering mind bending options and notice that I have not even mentioned Microsoft Fabric and AI Foundry!
"Fabric's data agents can now integrate with Azure AI Foundry via the Azure AI Agent Service"
